The elastic region is provided in at least one of the mounting part, the bases and the extending end portions of the arms.

Abstract: A hammer drill is provided with a connector equipped with a female terminal, movably between a connection position where the female terminal is located inside a plug-in port and a non-connection position where the female terminal is in retreat from inside the plug-in port. The hammer drill is also provided with a torsion spring that urges the connector toward the non-connection position. The connector is provided with a shutter portion that is located inside the plug-in port to close the plug-in port at the non-connection position and is in retreat from inside the plug-in port at the connection position. A dust collecting device is provided with a press rail that comes into abutment on the connector to move the connector to the connection position against the urging of the torsion spring as the dust collecting device is mounted.

Abstract: It is an object of the invention to provide a power tool that effectively prevents leakage of lubricant while regulating the internal pressure of a housing space for a driving mechanism. The object can be achieved by a representative power tool that includes a too bit 119, a driving mechanism 113, 115, an enclosed housing space 107a which houses the driving mechanism and in which lubricant is sealed in, and a path 151 which regulates pressure of the housing space 107a. On the path, a filter chamber 154 having a predetermined capacity, an inner passage 155c that communicates the filter chamber 154 with the housing space 107a, and an outer passage 159c that communicates the filter chamber 154 with the outside are formed. A filter 157 is disposed in the filter chamber 154 and spaced apart from a peripheral edge of an opening of the outer passage 159c which is open to the filter chamber 154, so that a space 161 is created on the opening edge side of the filter chamber 154.

Abstract: A power tool storage case includes a main case that has a tool storage portion, a battery storage portion and a charger storage portion, and a lid that can open and close the main case. The charger storage portion is a dual-purpose storage portion that can hold one of a charger and a battery pack in accordance with selection of one of the charger and the battery pack.

Abstract: A power tool according to the invention includes a dynamic vibration reducer having a body, a weight and elastic elements. The body is formed by a plurality of cylindrical members which are coaxially disposed to face each other. The elastic elements exert biasing forces on the cylindrical members such that the cylindrical members are held apart from each other. The cylindrical members are fixed to the tool body side under the biasing forces of the elastic elements. Venting members for forced vibration are provided on the cylindrical members and protrude radially outward from the cylindrical members, respectively. The venting members are mounted by inserting into venting member mounting parts on the tool body side in a direction transverse to the longitudinal direction of the cylindrical members. At least one of the venting members can move with respect to the cylindrical member in the longitudinal direction.

Abstract: A power tool includes a mode switching device that includes a mode switching member turned by manual operation, a linearly moving driven-side member and a mode switching mechanism actuated by linear motion of the driven-side member. The actuating member is disposed on the mode switching member such that the initial position of the actuating member is located in a position displaced in a radial direction from the rotation axis of the mode switching member. When the mode switching member is turned, the actuating member revolves in a circular arc movement in contact with the driven-side member to linearly move the driven-side member. The actuating member is structured to move radially inward of the mode switching member from the initial position toward the rotation axis of the mode switching member with respect to the mode switching member.
